Thanks for the link caetano.
So, since my requirement dates would make it impossible for the system to go with backward scheduling (start date in past not allowed) the order is scheduled based on forward scheduling.
We have MRP that runs once a day so will the delivery date change every day when the planning run is over ? this would in turn change the release date right ?
what made me ask is, the Procurement proposal was generated on 20.06.2014 .Based on which the system would have proposed a delivery date to 25.07.2014 (purchasing processing time + PDT). Now i see the date to 30.07.2014. Is this because of the MRP rescheduling ? will i have a new date (delivery date) when MRP runs tomorrow ?
If so can the changes be tracked ? well i don't see any changes in the purchase requisition.

Rahul
